Abstract: Based on the meteorological observation data from 1971 to 2008,climate effect on the growth of cherry was investigated in this paper,considering the growth and development conditions in Lianyungang.The main characteristics and occurrence of meteorological disasters which influence the growth of cherry were the main focus in this research.It showed that the climatic conditions in Lianyungang were suitable for the growth of large cherry especially from April to June,which was the fruit maturity period with high temperature,few rainwater,sufficient illumination and huge temperature difference between day and night.All these conditions above ensured the quality of the fruit.However,the fruit was easy to suffer from the spring frost,drought,heat,hail and other disasters.With the expansion of the greenhouse effect,the spring frost in Lianyungang City had the tendency that ends earlier and damages less,while the last frost date may still occur later.The greenhouse effect also brought the growth period of crop generally ahead of schedule.After sprouting,the cherry's ability of cold resistance became weak,so later the cherry encountered the frost,the larger the damage would be.Hail mainly occurred from April to August,especially from May to June the hail occurred mostly,which was the period for the cherry grows from blossom to ripened fruit.As a result,the hail can easily cause yield losses.Moreover,in Lianyungang,the drought was prone to happen from March to April,as well as early June to mid-July,which may influence the flower budding of large cherry.The summer rainstorm was also one of the meteorological disasters which reduce the production of large cherry.
